TRAINLSTOPPING DEVICE.

Application filed March 27, 15324.

To (ZZZ whom it may concera:

Be it known that I, MICHAEL MUHA, J12, a citizen of the United States, residing at East Chicago, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Train-Stopping Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to train stopping devices and it is an object of the invention to provide a novel and improved device of this general character whereby a train is automatically brought to a stop after the same has passed a predetermined point upon a trackway.

It is also an object of the invention to provide a novel and improved device of this general character wherein the same is caused to operate under the influence of a movable member positioned adjacent the trackway and which is thrown into operative position upon the setting of a danger signal, derailer or the like.

The invention also has for an object to provide a novel and improved device of this general character wherein a rock lever is carried by the locomotive and which is operatively engaged with a valve imposed in the line of an air brake system leading to the engineers valve and whereby the movement of the rock lever in one direction serves to adjust the first named valve in a position to set the brakes.

The invention also has for an object to provide a novel and improved device of this general character wherein means is employed for normally maintaining the rock lever against movement and to offset any minor contact which. may be had therewith such as snow.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved train stopping device whereby certain important advantages are attained and the device is rendered less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the ac companying drawings, wherein is disclosed Serial No. 702,445.

a somewhat diagrammatic view in elevation illustrating a train stopping device constructed in accordance with an embodiment of my invention.

As disclosed in the accompanying drawings, R denotes a rail of a trackway supported in a conventional manner upon the ties T and suitably secured to one of the ties is the plate P positioned in predetermined proximity to the rail R. The plate P has pivotally engaged thereto for rocking movement in a vertical path the trip member 3 provided with a rock arm 5 extending below the plate P and with which is opera tively engaged the arm 6. The arm 6 is also operatively engaged with the rod 7 disposed longitudinally of the rail R and adapted to have endwise movement imparted thereto upon the setting of a block or of a derail. As this particular means in itself forms no part of my invention, it is thought that a detail description and illustration thereof is unnecessary other than to state that upon the setting of a block or derail, the rod 7 moves in a direction toward the plate P whereby the trip member 3 will be caused to assume substantially a vertical position so that the same will be in the line of travel of the lower extremity of the rock lever L carried by the locomotive.

The lever L is pivotally supported intermediate its length in any suitable manner by a locomotive and has its upper extremity operatively engaged, as at 9, with a two-way valve 10 interposed in the release line 11 of an air brake system leading to the engineers valve so that when the lever L is caused to rock in contact with the trip member 3, the valve 10 will be so adjusted as to cause the brakes to be automatically set whereby the train will be brought to a standstill should the engineer pass from one block into another when the danger signal or derail may be set.

I also find it of advantage to provide the lever L preferably at a point below its pivot with the opening 14: through which a wire pin 15 or other fragile member may be passed, the same being also suitably held by the locomotive. This pin 15 serves to normally hold the lever L against rocking movement except in the event that the lower end portion of said lever should contact with snow or the like, but this pin 15 will readily break and sever when the lever L strikes the upstanding trip member 3.

From the foregoing description it is thought to be obvious that a train stopping device constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish a vertically disposed rock lever having its upper end portion operatively engaged with the valve whereby a movement of the rock arm in one direction moves the valve to open position, and a breakable member disposed directly through the rock lever for normally holding said rock lever against movement.

2. A valve controlling device comprising a vertically disposed rock lever having its upper end portion operatively engaged with the valve whereby a movement of the rock arm in one direction moves the valve to open position, the lower end portion of the rock lever being provided with an opening, and a fragile member disposed through said opening for normally holding the rock lever against movement.

In testimony whereof I hereunto afiix my signature.
